The skeletal system, along with muscles, helps the body do this essential action.
What is movement?
This muscle is responsible for pumping blood throughout the body.
What is the heart?
This type of joint allows for no movement.
What is a fibrous joint?
This common bone condition is characterized by low bone density.
What is osteoporosis?
This bone group is composed of the mandible, maxilla, and occipital bones, among others.
What is the skull?
The skeletal system stores this essential mineral needed for strong bones and muscle function.
What is calcium?
Muscles contract when this energy molecule is broken down, providing the necessary power for movement.
What is ATP (adenosine triphosphate)?
This joint connects the femur and the tibia.
What is the knee joint?
This common joint condition causes pain, stiffness, and inflammation, sometimes leading to bone spurs.
What is arthritis?
The pubis, coccyx, ischium, ilium, and sacrum make up this bone structure.
What is the pelvis?
This structure, composed of the sternum, ribs, and vertebrae, protects vital organs like the heart and lungs while aiding in respiration.
What is the thoracic cage?
The three types of muscle in the human body are skeletal, cardiac, and this.
What is smooth muscle?
This type of joint allows movement in only one direction.
What is a hinge joint?
This common bone condition is characterized by low bone density.
What is osteoporosis?
This bone, shown in this image, is the longest, strongest bone in a human body.
What is a femur bone?
The human body has this many bones at birth, but some fuse together as we grow.
What is 300?
This protein blocks myosin-binding sites on actin filaments, preventing muscle contraction until calcium is present.
What is tropomyosin?
The shoulder and hip joints allow a wide range of motion because they are this type of joint.
What is a ball-and-socket joint?
This type of absorptiometry is used in diagnoses for osteoporosis
What is dual-energy X-ray absorptiometry?
Bone is also known as the shoulder blade.
What is the scapula?
Number of bones in an adult human skull.
What is 22?
This muscle relaxes or opposes the movement of the agonist.
What is an antagonist?
This substance exists within joints, helping to reduce friction and keep them moving smoothly.
What is synovial fluid?
Osteoporosis occurs when these bone-resorbing cells outpace bone-building cells, leading to weakened bones.
What are osteoclasts?
Bones shown in pink.
What are the metacarpals?
